IMPROVBD DOOR. I'AS'IENING.

Beit known that I, MATTHEW BENNETT, of Kilbourne City, in Columbia county, and State of Wisconsin, have invented a new and improved Door Fastener or Lock, to be used on doors/anden drawers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyingvpatterns, and to the gures of reference marked thereon.

Four things are necessary to the design of the said door fastener or lock, which four things are each claimedto be new and original inventions, and without any one of which the said door fastener or lock would be incomplete, viz

1. A spring-latch marked 1, in the parcel labelled patterxis," one end of which is made like the blade of a lance; after boring a suitable depth into thedoor, the lance end of the latch is driven intothe solid wood three-fourths of an inch, as per model.

2. A bolt marked 2, in the parcel marked patterns, uniting the knobs and working under and raising the latch marked 1; an enlarged width in the centre of the bolt is required, as may be seen in the wooden pattern, and this enlarged width is claimed as new and valuable in its application, as may be seen by an examination of the model. A l' 3. A stop or fastening .narked 3,. in the parcel labelled patterns-Y Those applicable to bolts moving horizontally cannot be applied to bolts moving perpendicularly; hece a new, simple, and eicient stop or fastenin g has been invented, the construction and operation o'f which are explained as follows: The stop is constructed in the form of a capital L In the centre of the long arm of the L, on the under side, is a notch which is intended to take hold of the plate on the outside, to keep it from passing back. The wood is so cut away in the door as that the part of the L or stop falls a little below the spring-latch when pushed in beyond the latch; and when the stop is drawn out the door is fastened; the latch cannot raise, as will be seen by reference to the model sent herewith. A

4. A spring-catch marked 4, in the parcel marked patternsf In order not to cut or mar the casing of the door, a spring-catch has been invented which gives way to the door till the latch marked 1 is opposite to the mortise in the catch, when the latter flies forward, takes the latch, and sinks into the plate o n the door, which is counter-sunk. The model exhibits the catch made in a cheap mode; but a neater mode of making'them may be seen by reference to pattern marked 4. Iron is sufficiently elastic for all the springs.

Both the spring-latch and spring-catch are claimed as new and valuable inventions, intended to supersede the spiral and other springs, and the complicated arrangements of locks and fastenin gs now in use, which are expensive and liable'easily to get out of repair; and the wide knob-bolt and stopy are claimed as new and valuable inventions, and are necessary to work the spring-latch and spring-catch aforesaid, and give them any actual value.

I claim the-combination of the devices constructed and arranged as described.

MATTHEW BENNETT.
